Procurement Notes

Verify the specific suffix /51 against the manufacturer's current datasheet to confirm packaging quantity and tape-and-reel specifications. Ensure that the component status remains active, as production statuses for Vishay diode series are subject to change. Cross-reference the ordering part number with official distributor catalogs to validate availability and lead times prior to procurement planning.

Selection Notes

Select this component when a 4A current rating and 400V blocking voltage are required in a surface-mount footprint. Evaluate the thermal resistance parameters relative to the PCB copper area to ensure adequate heat dissipation. Confirm that the operating frequency and surge current requirements align with the device's specified limits for reliable long-term operation.

Part Context

This component belongs to Vishay's GBU series of surface-mount bridge rectifiers. The series offers various voltage ratings and current capacities within the same mechanical outline. The M3 suffix indicates compliance with RoHS standards and absence of halogens. The /51 suffix typically denotes a specific reel size or packaging variant defined by the manufacturer.
